NEW VARIABLE ROTOR POROSITY SERIES FROM RHE
We have introduced the new rotor variable porosity series into our range of heat wheels.
They continue to have the same design and overall dimensions of all our other series S426, S430 and S436. This new variable series is custom built to a selected porosity between the existing two extremes of S426 (low porosity, more Mylar, higher efficiency at higher pressure drop) to S436 (high porosity, less Mylar, lower efficiency lower pressure drop).
This is achieved by varying the small spacing between the Mylar layers to better match the specific design performance of efficiency and pressure drop of a particular project. This effectively increases or decreases the total length of Mylar film wound thus increasing the total surface area for heat transfer between hot and cold air flow streams per wheel diameter.
In order to promote and encourage the optimum sustainability solution our price is only dependant on rotor size irrespective of rotor series. This allows the designer or customer to make the optimum efficiency/pressure drop or energy vs running cost choice at no extra capital cost.
